Abstract: A system is implemented on a wireless network for adjusting a forward link power control parameter based on forward link feedback. A wireless unit is in communication with several base stations during soft handoff, and provides feedback relating to forward link quality, e.g., forward link pilot signal strength or traffic channel frame error rate. The feedback is compared to a comparison or reference point (such as target frame error rate, or a maximum pilot signal strength in the active set) chosen for gauging the quality or nature of the feedback for power control purposes. Based on this comparison, a power control parameter of one or more of the base stations may be adjusted upwards or downward. The power control parameter may be a forward link reference transmit power level “Pref” used to control base station power transmission levels in the presence of power control bit errors.

Abstract: In the method, a phase of at least one signal transmitted from a transmit antenna of a base station is shifted based on a sweeping frequency having a differentiating component.

Abstract: A method for link quality control in a wireless communications network includes determining whether an indicator of link imbalance exists among a plurality of base stations associated with a mobile unit, and implementing a control action to help prevent at least one of fading or signal cutoff between the mobile unit and at least one of the base stations, if the indicator indicates that link imbalance exists.

Abstract: In the method, a signal power to interference metric for a communication channel in a coverage area of a phase sweep diversity communication system is predicted based on a sweep frequency for transmissions in the coverage area.

Abstract: An educational game is described for teaching time concepts (e.g., hours in a day, days in a week and month, calendar months, and seasons). The game comprises puzzle pieces which can be assembled in interconnecting relationship in inner and outer bands. The pieces in one band designate seasons and the pieces in the other designate calendar months. The individual pieces are so configured that assembly thereof is only possible if the seasons and the months are both in the correct sequence and the interrelationship between the seasons and the calendar months corresponding to each season is established correctly. The pieces designating months house removable pegs or like markers corresponding in number to the days in the designated months and removable for placement on associated calendar month matrices.An optional feature of the same is a day rod advantageously adapted to be mounted within the inner band of puzzle pieces.
